Narrated Khuraym Ibn Fatik:
The Messenger of Allah ﷺ offered the morning prayer. When he finished it, he stood up and said three times: False witness has been made equivalent to attributing a partner to Allah. He then recited: "So avoid the abomination of idols and avoid speaking falsehood as people pure of faith to Allah, not associating anything with Him.
حَدَّثَنَا يَحْيَى بْنُ مُوسَى الْبَلْخِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، حَدَّثَنِي سُفْيَانُ، - يَعْنِي الْعُصْفُرِيَّ - عَنْ أَبِيهِ، عَنْ حَبِيبِ بْنِ النُّعْمَانِ الأَسَدِيِّ، عَنْ خُرَيْمِ بْنِ فَاتِكٍ، قَالَ صَلَّى رَسُولُ اللَّهِ ﷺ صَلاَةَ الصُّبْحِ فَلَمَّا انْصَرَفَ قَامَ قَائِمًا فَقَالَ " عُدِلَتْ شَهَادَةُ الزُّورِ بِالإِشْرَاكِ بِاللَّهِ " . ثَلاَثَ مِرَارٍ ثُمَّ قَرَأَ { فَاجْتَنِبُوا الرِّجْسَ مِنَ الأَوْثَانِ وَاجْتَنِبُوا قَوْلَ الزُّورِ * حُنَفَاءَ لِلَّهِ غَيْرَ مُشْرِكِينَ بِهِ } .
